How to read a listing like an underwriter

A listing is a piece of marketing. That isn’t a criticism; it’s its job. But in commercial and investment real estate, nobody buys from the brochure. A lender’s underwriter reads the same property file looking for one thing: what could go wrong, and what it would cost. That habit is worth bringing to a home purchase.

1. Read what isn’t there

If a listing mentions a new kitchen but says nothing about the roof, the furnace or the windows, that silence is information. Ask for the age of every major system and for receipts. “Updated” with no year attached usually means “not recently”.

2. Price the next ten years, not the next ten days

A roof, a furnace, a condo special assessment and a basement waterproofing job can together cost more than the gap between two homes you’re comparing. Put a rough number and a year on each, and the “more expensive” house is sometimes the cheaper one.

3. Check the paperwork behind the photos

A basement apartment is only an income suite if it’s legal. A finished basement, an addition or a deck may or may not have permits. In Toronto you can request a property’s building permit history from the City; for a condo, the status certificate tells you about the reserve fund, lawsuits and upcoming increases.

4. Separate the house from the market

Comparable sales tell you what the market paid. They don’t tell you whether those buyers checked the things above. I look at comparables to set a price range, then adjust for condition and risk, not for staging and lighting.

5. Decide your walk-away number before you fall in love

Underwriters set limits before they see the deal, so the deal can’t talk them out of it. Write your maximum down before the offer date. If the house goes beyond it, it was somebody else’s house.

The Home X-Ray checklist turns these habits into a list you can tick through at a showing.
